SAFETY
Running outboard too fast (Overspeeding)
•
“Too fast” means running faster than outboard normally runs on boat.
Running outboards: Exhaust fumes
•
Whenever running the engine, assure there is proper ventilation to avoid the accumulation of carbon
monoxide (CO), which is odorless, colorless, and tasteless, and can lead to unconsciousness, brain
damage, or death if inhaled in sufficient concentrations. CO accumulation can occur while docked,
anchored, or underway, and in many confined areas such as the boat cabin, cockpit, swim platform,
and heads. It can be worsened or caused by weather, mooring and operating conditions, and other
boats. Avoid exhaust fumes from the engine or other boats, provide proper ventilation, shut off the
engine when not needed, and be aware of the risk of backdrafting and conditions that create CO accu-
mulation. In high concentrations, CO can be fatal within minutes. Lower concentrations are just as
lethal over long periods of time.
DANGER
DO NOT run the engine indoors or without adequate ventilation or permit exhaust fumes to
accumulate in confined areas. Engine exhaust contains carbon monoxide which, if inhaled,
can cause serious brain damage or death.
Running too fast can happen when:
1) Using a flushing device...
Turn on water before starting outboard.
Keep engine speed below 2000 RPM.
With no load, outboard will run too fast
very easily. Wear eye protectors.
2) Running with the
wrong test wheel...
This may happen if
outboard runs too fast.
Use the right
test wheel.
